While the 20-year-old starlet was singing her heart out, the front of her cut-out dress parted ways to expose her undergarments.

And with all the twirling and dancing Gomez did during her performance, images from the Daily Mail show the incident happened more than once.

But even though the concert goers did not seem to mind Gomez’s indecent exposure, there is one person who won’t be jamming out to the “Come & Get It” singer anytime soon.

According to TMZ, Gomez’s ex Justin Bieber has demanded that none of her music be played at the photo shoots he takes part in.

Among a laundry list of set demands, including no autographs or cell phones, the list made by Bieber’s team has one final demand: "No Selena music on set."

While the Biebs has been seen getting cozy with some new ladies recently, his Gomez music ban shows his young heart is still broken.

Last week it appeared Bieber had given up on trying to woo Gomez back when he was spotted having a major PDA session with a Las Vegas waitress.

However, it appears that relationship has no future, as Jordan Ozuna, who was identified as the woman with whom Bieber was seen kissing at an indoor skydiving facility in Sin City last week, is very much a married woman.
